And on Instagram, Krystal Parrish wrote, "When your Southwest flight crew celebrate a plane full of kickass women and men going to the Women's March by lighting it up!!"

A spokesperson for Southwest Airlines tells Mashable:

"While we're unaware of details surrounding a specific flight, our flight crews celebrate, commemorate, acknowledge and share in special moments with our customers all the time. Some of our aircraft are equipped with mood lighting and while this was not a companywide initiative, at times, our flight crews will adjust the lighting for a customer or group of customers traveling on their flight. For example, in October, one of our flight crews changed the lighting to honor a breast cancer survivor onboard their flight."

Per the New York Times, march organizers expect a turnout of more than 200,000 people, while local law enforcement have planned for as many as 400,000 people to march.

The event is scheduled for president-elect Donald Trump's first full day in office. He is expected to be sworn in as president at about noon on Friday.
